HARROW.

SPECIFICATION forming part of Letters Patent No. 383,305, dated May 22,1888.

Application filed November 12, 1887. Serial No. 255,008.

To aZZ whom it may concern.-

Be it known that I, PETER 0. KING, a citizen of the United States, and aresident of Sycamore, in thecounty of \Vyandot and State of Ohio,haveinvented certain new and useful Improvements in Harrows; and I dodeclare the following to be a full, clear, and exact descrip tion of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to letters or figures of reference markedthereon, which form a part of this specification.

Figure 1 of the drawings is a representation of this invention, and is atop view. Fig. 2 is a cross-section taken where the broken line :0 a: ismarked on Fig. 1. Fig. 3 is a vertical section taken where the brokenline a z is marked on Fig. 1. Fig. 4. is a detail.

The invention relates to improvements in barrows; and it consists in theconstruction and novel combination of parts, hereinafter described,illustrated in the drawings, and pointed out in the claim.

Referring by letter to the drawings, A represents the parallel beams ofa harrow, usually four in number, having an open space between them ofabout four inches.

The beams A are designed to carry the teeth B, and for that purpose areprovided with openings a, placed in two series parallel with the edgesof the beams, the members of each series being equidistant, and themembers of one series alternating with the other. The openings atincline downward and rearward through the beams. The beams A have aslight downward pitch toward the rear of the harrow. The teeth B arepreferably made diamond-shaped, and are tightly fitted in the openingsa, which gives them the rearward pitch necessary for the purposehereinafter specified. The teeth B are made sufficiently long to projectabove and below the beams A, the upper projection, 1), allowing theteeth to be driven down as the lower end or point, I), becomes worn.Hooks or staples a are fastened in the usual manner to the outer edge ofthe front beam for the reception of the draft chain.

0 are cross pieccs rigidly bolted, as shown (No model.)

at c, to the beams A at points equidistant from their ends. Thecross'pieces U have beveled portions (Z on their lower facecorresponding to the pitch of the beams, the shoulders b abuttingagainst the front edges of the beams. This construction of thecross-pieces relieves the bolts 0 from considerable strain. Runners D,having the rounded front ends, are bolted to the inner edges of thecross-pieces G. The runners project above the level of the upperprojecting portion of the teeth, and are de signed for the convenienceof drawing the harrow from one field to another, it being only necessaryto reverse or turn the harrow upside down and draw the harrow in themanner of a sled.

In heavy ground it is often necessary to weight the harrow, and as theweight of the driver may be suflicient the removable seat E is provided,secured to the downward and for ward projecting standard F. The outerend of the standard F is inserted in an iron clip, 6, passing throughthe front beam near its edge. A pin, f is inserted through an opening inthe standard and beam forward of the clip e,which prevents the standardfrom being accidentally detached.

Below the seat E a downwardly curved spring bar, G, is provided, thecentral portion of which passes through the transverse opening in thestandard F. The outer ends of the curved spring-bar are provided withthe shoulder portion 7/, turned vertically down ward,and enter socketsIt in one of the beams. The seat being removable, allows the harrow tobe re versed, for the purpose before described.

The beams A and teeth 13, as before stated, are placed on a bevel orincline, and by being so arranged the ground is completely broken,pulverized, and cultivated.

A harrow constructed as above described is very durable, cheap, andeasily transported from field to field.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s

In a harrow, the combiuation,with the beams having the runners securedthereon, of the seat having the end of its standard inserted in a clip,a, and secured by a pin, f, passing through an opening in the standardand beam In testimony whereofI affix my signature in forward of theclip, and the downwardlypresence of two witnesses.

curved spring-bar G, engaging centrally with the standard below the seatand having its PETER 0. KING. ends provided with the shoulder portion h,

and turned centrally downward to enter the WVitnesses:

sockets h in the beam, the seat thus being GEORGE HAYMAN,

rendered removable, substantially as specified. A. E. BENNINGTON.
